that virtually every curtain wall will leak; it is only a matter of when, where, and what it will cost<br />

to fix. Developed by Dr. Raymond Ting, TingWall utilizes an “air loop” principle to neutralize the<br />

effects of both wind and rain by incorporating separate air and water seals. The result is a curtain<br />

wall system that can tolerate imperfect seals anywhere in the system and still not leak. TingWall<br />

has surpassed the most rigorous AAMA standards in multiple tests, and can withstand greater<br />

seismic and wind loads than a conventional system. TingWall is designed to allow for the use of<br />

multiple facing materials without edge conflicts, and is cost c<strong>om</strong>petitive with so-called “stick”<br />

systems.<br />

Water-Repelling Paint<br />

The leaves of the lotus flower are water-repellent. After a shower of rain they immediately appear<br />

dry and clean, as water runs off them like marbles off a glass plate. Lotusan has duplicated this<br />

effect, one of nature’s own inventions which has proved itself over millions of years, in a new<br />

silicone facade paint. Lotusan c<strong>om</strong>bines the well-known water-repellent properties of silicone<br />

paints with a surface micro-structure based on the lotus leaf. This considerably reduces the<br />

contact area for water and dirt, and adhesion is also greatly reduced. The result is that dirt<br />

is repelled by water droplets and facades stay dry and clean - even highly stressed weatherexposed<br />

facades. The lotus effect was discovered by Prof. Dr Wilhelm Barthlott of Bonn University,<br />

a scientific achievement in the field of biology which created a worldwide sensation.<br />

Wind Sculptures<br />

Ned Kahn is an acc<strong>om</strong>plished North California sculptor who deploys materials in order to celebrate<br />

and amplify natural forces. His large-scale wind installations, which have names like Wind Portal,<br />

Technorama Facade, and Fragmented Sea, utilize vast arrays panels made of aluminum, steel,<br />

and other materials to shimmer and dance in the breeze, allowing the natural environment<br />

to influence the design. In Articulated Cloud, for example, thousands of 9-inch squares of<br />

perforated aluminum are mounted on low friction hinges so that the entire surface of the facade<br />

responds to the wind. Each moving panel is perforated with thousands of different sized holes<br />

that, when viewed fr<strong>om</strong> a distance, create a photographic mosaic of sand dune images. When<br />

sunlight passes through the screens, intricate shadow images of the dunes are projected onto<br />

the walls and floor of the building lobby.<br />

Lumisty Film<br />

Lumisty first drew widespread attention when it was used on the windows of Pleats Please, Issey<br />

Miyake’s clothing boutique in SoHo. Since then many of the world’s top designers and architects<br />

have opted to put the film at the service of their own rich imaginations, and the results have been<br />

stunning. Lumisty’s applications range fr<strong>om</strong> museums, hotels, banks, restaurants, and bars, to<br />

storefronts, conference ro<strong>om</strong>s, trade show exhibits-and even bathro<strong>om</strong>s. If you’ve seen Lumisty<br />

in action you’ve experienced the unexpected visual sensation it creates. Upon first encountering<br />

the product, people are often struck by what they think is an optical illusion. Walking past a<br />

window with Lumisty applied, a perfectly clear, transparent glass surface bec<strong>om</strong>es, in a step<br />

or two, partially fogged. Two or three steps later, the same window is c<strong>om</strong>pletely fogged. Walk<br />

backward or forward, and it’s clear again. As the viewer’s angle shifts, so does the transparency<br />

or translucency of the film.<br />

SmartGlass<br />

Suspended Particle Device (SPD) technology is a “switchable” light-control technology that has<br />

numerous performance and cost advantages over other technologies. SPD-Smart products allow<br />

you to instantly and precisely control how clear or dark glass or plastic is, and to easily adjust<br />

the light transmission of the product manually or aut<strong>om</strong>atically. This is made possible by a thin,<br />

flexible SPD film invented by Research Frontiers. Available as a film or already incorporated into<br />

glass, SPD film can be easily adapted to a variety of products that people use every day, such as<br />

architectural windows, aut<strong>om</strong>otive windows, sunglasses, display screens for laptop c<strong>om</strong>puters,<br />

cellular telephones, instrument panels, electronic games and point-of-purchase and advertising
